As a developer, I totally agree and want to second Peter's request
(for example, when reporting issues with Bookworm on the issue tracker
at
http://code.google.com/p/threepress/issues/list).
If you supply an epub, we can much more easily write tests to confirm
that the behavior has been corrected. Since both projects are open
source, it would be best to include a document that you don't mind
being part of the open source code itself, as e.g. Bookworm ships with
its entire test suite under the BSD license.
